雅思写作Task 1中的线图(Line Graph)是常见题型之一,要求考生在20分钟内完成至少150词的描述,线图通常展示随时间变化的趋势,考生需准确捕捉关键特征、比较数据差异,并用恰当的语言表达,本文将结合最新数据案例,解析高分技巧。
线图写作核心结构
引言段(Introduction)
用1-2句话改写题目,说明图表主题、时间范围和单位,避免直接抄题,可替换同义词或调整句式。
例句:
"The line graph illustrates changes in the proportion of renewable energy consumption in four European countries between 2010 and 2022."
概述段(Overview)
提炼2-4个最显著趋势,不涉及具体数据,重点关注:
- 最高值/最低值
- 总体上升或下降趋势
- 交叉点或显著差异
示例:
"Overall, Germany consistently had the highest renewable energy usage, while France showed the least growth. All countries experienced an upward trend, except for Italy after 2018."
细节段(Details)
分2-3段描述具体数据,按趋势或国家分组,注意:
- 使用数据支撑描述(如百分比、年份)
- 比较相似或相反的趋势
- 避免罗列所有数据,选择关键节点
